Is there a way to tell what gears are in the rear end of my car? When I bought my car the gentleman told me that it had 3:55's. That wasn't a selling point on that car for me, but something that I do want done. However I really don't know for sure that they are. Any suggestions?:confused:

a 3.55 will run about 2200 rpm at 60mph.

jack the rear of the car up in the air and make sure the parking brake is off and the car is in neutral. then by hand spin the drive shaft until the tires turn one complete revolution. if they are 355 it will take approx 3.5 turns of the drive shaft for one turn of the tire. i have done that many times.
